CONTROLS
Technical Data concerning ethanol fuel. Methanol
fuel is not allowed. Do not use E85 alcohol based
fuel. Damage to the engine and components may
occur.
When operating in temperatures below 32°F
(0°C), use fresh, clean winter grade gasoline to
help insure good cold weather starting.
IMPORTANT INFORMATION Experience
indicates that alcohol blended fuels (called
gasohol, ethanol or methanol) can attract
moisture which leads to separation and
formation of acids during storage. Acidic gas
can damage the fuel system of an engine while
in storage. To avoid engine problems, the fuel
system must be emptied before storage of
thirty days or longer. Drain the gas tank, start
the engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel the next
season. See Storage for more information. Do
not use engine or carburetor cleaners in the
fuel tank or permanent damage may occur.
WARNING! Gasoline is highly flammable.
Observe caution and fill the tank outdoors (see
the safety section).
WARNING! The engine and the exhaust
system, become very hot during operation.
There is a risk for burns if touched. Let engine
and exhaust system to cool before refueling.
